About Rad At Hand
Rad At Hand is a free educational resource designed for radiology trainees, practicing radiologists, and medical professionals. The platform aims to deliver high-quality, interactive tools and guideline-based calculators that support clinical decision-making and structured learning.
Our tools cover a wide range of radiologic tasks, including:
- Solid organ evaluation: Volume calculations, parenchymal texture, and organ indices for the liver, spleen, kidneys, and more.
- ACR reporting systems for cancers: TI-RADS for thyroid nodules, O-RADS for ovarian masses, PI-RADS for prostate, and LI-RADS for liver lesions.
- Trauma scoring systems: AAST injury grading and AO Spine classification tools.
- CAD-RADS: Coronary Artery Disease Reporting and Data System calculators and reporting support.
- Vascular imaging tools: Including NASCET criteria for carotid stenosis, PESI score for pulmonary embolism, renal resistive index, and other hemodynamic indices.
- Incidentalomas: Guidance for incidental radiologic findings based on the latest American College of Radiology (ACR) white papers and consensus guidelines.
Rad At Hand also includes Radiology CaseBank, a free, interactive library of real-world imaging cases designed to build confidence and improve interpretation skills for residents and medical students.
About Dr. Pooyan Khalighinejad
Dr. Pooyan Khalighinejad is a radiology resident and nuclear medicine physician at UT Southwestern Medical Center, and an incoming neuroradiology fellow at Johns Hopkins University. He is the founder of Rad At Hand and has been actively involved in radiology education and research for over 15 years.
His academic focus includes:
- Advanced imaging of the brain
- Development and application of zinc-sensitive MRI contrast agents
- Functional imaging of endocrine organs like the pancreas and prostate
- Photon counting CT and radiomics
- Artificial intelligence in diagnostic imaging
Dr. Khalighinejad has authored numerous peer-reviewed publications and has presented at major radiology conferences including RSNA, SABI, and ARRS. He is the recipient of multiple awards, including SABI’s Best Project Award for Radiology CaseBank.
